AutoPkg recipes for OS X Lion and OS X Mountain Lion OS installers now available

Now that Apple has made direct download links available for Lion and Mountain Lion, I’ve written AutoPkg .download and .pkg recipes for the following OS X installers:

These recipes will download the disk images linked to the relevant KBase articles, extract the installer packages stored inside the disk images and rename the disk images and installer packages with the OS name and version number.

One thing to be aware of is that the downloaded installers do not themselves install the relevant version of OS X. Instead, they install the Install.app for that version of OS X into the /Applications directory.

Another thing to know is that the downloaded installers are signed using Software Update signing certificates which expired in 2019. As of June 30th, 2021, I do not know if Apple is planning to re-sign the installers with the current Software Update signing certificate.

One of the consequences of this is that I cannot use AutoPkg’s code signature verification as part of the AutoPkg recipes, since AutoPkg’s current code signature verification will error when it hit the expired certificates. If Apple does choose to re-sign these certificate with valid non-expired signing certificates, I’ll add code signature verification to the recipes.

If you do need to use these installers, setting the system clock on your Mac to a date and time before the October 24th 2019 expiration date will allow these certificates to appear as valid again and any expiration-related issues should go away.
